In my mechanic-ing experience, starting in the early 70's, parts substitutions are the norm in production bike building, and that goes double for anything produced in Europe before 1980! I have seen Nervex Professional, BCM, Carlton Capella, Prugnat 62 and Prugnat long-point used on Raleigh sub-International models--Competition and Gran Sport. Huret dropouts I've only seen on 1972 and later Competitions, but I'd believe almost any variation on that model and on the Gran Sports. Gran Sports especially seemed to take frame parts potluck and components potluck in a big way. This sounds like an early 70's Competition or GranSport to me. Here's another one: 1968 or 1969 Gran Sports, chrome with yellow painted trim panels, Huret Alvit or Luxe derailleurs, and Zeus cranks!
